1.Show that the points (5,5),(6,4),(-2,4) and (7,1) are concyclic .Also find the equation ,centre and radius of the circle on which they lie.​

(5,5),(6,4),(-2,4) and (7,1)

Step-by-step explanation:

are concyclic

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
